If moose disappear from the boreal forest of northern Minnesota, as some biologists predict, they will not exit with a thunderous crash. Climate extinctions come quietly, even when they involve 1,000-pound herbivores.
Experts who have studied the Northwestern moose — Alces alces andersoni — believe they are witnessing one of the most precipitous nonhunting declines of a major species in the modern era, yet few outside Minnesota fully appreciate the loss.
The moose is an iconic species whose existence is woven into the social, economic and cultural fabric of this region. Its elongated head and wide antlers are emblazoned on everything from T-shirts to tire flaps. The 1960s cartoon character Bullwinkle J. Moose and his flying squirrel friend Rocky were residents of the fictionalized town of Frostbite Falls, Minn.
But the animals that inspired Bullwinkle are not what they were. Here, even healthy bulls — whose size, strength and rutting prowess make them the undisputed kings of the North Woods — are dying from what appear to be a combination of exhaustion, exposure, wasting disease triggered by parasites and other maladies.
The biologists are baffled and also helpless.
Mark Lenarz, who retired in March from the Minnesota Department of Natural Resources (DNR), where he led moose research efforts, said it’s not like the TV show “CSI: Crime Scene Investigation.”
“Unlike ‘CSI,’ it’s very hard to identify in the field exactly what an animal is dying from,” he said. “We know something about the symptoms” of distressed moose, he added, “but we don’t necessarily know the exact causes of mortality.”
What Lenarz and other experts do know is that a variety of climate stressors — including higher average annual temperatures, a long string of very mild winters, and increasingly favorable conditions for ticks, parasites and other invasive species — are conspiring to make northern Minnesota a moose graveyard.
Since 2002, Minnesota DNR specialists have put radio collars on 150 healthy adult moose; 119 subsequently died, most of them from unknown causes, according to wildlife officials. Car and train collisions accounted for 12 mortalities, while wolves were culpable in just 11 deaths.
Sudden collapse of herds
Meanwhile, annual surveys taken from helicopter overflights show that the state’s primary moose population, in the state’s northeastern Arrowhead region, has been halved in just six years, dropping from 8,840 animals in 2006 to just 4,230 this year. The decline mirrors a similar collapse a decade ago in the state’s northwest corner, where moose plummeted from an estimated 4,000 animals in the mid-1980s to less than 100 by the mid-2000s.
While some monitoring of moose had occurred in the 1990s, most of the animals were gone before scientists could examine cause-and-effect relationships. In the Arrowhead, however, experts are watching mass mortality, discovering multiple moose carcasses in the same area, including animals that appeared relatively healthy only a few years before.
It’s not just the occasional sickly moose succumbing to common causes of mortality, said Lenarz. “We’re out in the
field collecting dead radio-collared moose, and we were finding other moose that had died along with them.”
Similar mysterious deaths of one or more moose have been documented in Voyageurs National Park, where the National Park Service had launched its own radio-collar study of the animals, and in the Boundary Waters Canoe Area Wilderness, where moose sightings used to be routine for visitors but are increasingly rare.

Editor’s note: Protecting the ocean means life protection, our ecosystems depend on intact and clean oceans. Even though the aim is to protect 30% of the planet, it’s not clear what conservation actually means worldwide. That leads to ineffective conservation measures and demands more knowledge about oceanic ecosystems and also implementing it. For the most part protected areas don’t need to be managed, they just need to have humans leave them alone.
By David Shiffman/Revelator
There’s never been more momentum for protecting the ocean, but new research finds that many efforts fail to protect endangered species — or have barely gotten off the drawing board.
Ocean ecosystems and the marine wildlife that depend on them are under threat as never before. Between overfishing, climate change, plastic pollution, and habitat destruction, it’s a bad time to be a prawn, cod, seabird, or whale.
There’s no single silver bullet solution to the biodiversity crisis, but in recent years, many people in the environmental community have focused on the goal of “30 x 30”: protecting 30% of the planet by the year 2030. Many nations have made promises toward that goal, including the United States, which has adapted it into the “America the Beautiful” initiative.
Measurable goals like this provide nations with clear, quantifiable conservation goals that others in the international community can follow, verify, or use to identify shortfalls and push for more action.
At the same time, many experts warn that number-based targets like “protect 30%” lend themselves to incentives to arguably-kinda-sorta protect as much as possible, rather than protecting the most ecologically important areas. Governments, for instance, can use what’s euphemistically referred to as “creative accounting” — counting things as protected that probably should not be considered protected.
Two new research papers examine some of this creative accounting in the ocean. Together, they stress important things to keep in mind when creating protected areas and when assessing their usefulness.
To Protect a Species, Protect Areas Where They Actually Live
A surprisingly common issue in area-based conservation happens when a government declares a new protected area to help save a threatened species of concern…without first checking to see if the species actually lives within those boundaries.
It happens more often than you might think. A new study published in the Journal of Animal Ecology looked at 89 marine protected areas in Europe that are supposed to protect diadromous fish species (those that migrate between ocean and fresh water, like salmon or some eels) of conservation concern.
Their findings are shocking: Many of these areas protect habitats where those fish species do not live, and very few of them protect the most important core habitat for any diadromous fish species.
“A marine protected area should be an area that protects part of the marine environment,” says Sophie Elliott of the Wildlife Conservation Trust, the study’s lead author. “I say ‘should’ because there are a lot of parks that don’t have enough thought put into them. Quite often things are done quickly without thinking or understanding the situation.”
Sometimes this happens because of limited resources for scientific study. In other words, according to Elliot, we simply don’t know enough about species’ habitat use to protect their key habitat, at least not yet. This is known as the rare-species paradox: Endangered species are often hard to find and study, especially in the vast ocean, so it can be hard to understand what habitat qualities they need to thrive, even if we can hypothesize that protecting certain regions will mitigate some of the threats the species face.
Other times government officials, in search of positive publicity, announce a new protected area that was studied but wasn’t intended to protect a species.
“We had a series of MPAs that were supposed to have measures in place to protect certain species,” Elliott says. “But then an extra species got tacked on to the stated goals of the MPA, and it wasn’t effective for that species.” She declined to identify examples, given the political sensitivities of some of these protected areas.
In addition to gathering more data and always basing protected-area design on the best available data, Elliott recommends a more holistic approach to designating future protected areas.
“When people think about putting MPAs in place, look at the whole range of biodiversity that exists within it, because there might be many endangered and protected species,” she says. “You need to know what’s in that MPA and do ecosystem-based management” — management focusing on the whole ecosystem and not just individual species. It’s the difference between protecting cod by establishing fishing quotas versus protecting cod by also managing their habitat and predators and food and other things that eat that food. “We’ve long been calling for that, but we aren’t really working toward it at all,” she says.
What Counts As ‘Protected’ Varies More Than You Think
Another key issue in marine protected area management is what should count as “protected.”
Some areas restrict oil and gas extraction but allow any and all fishing. Some allow swimmers and other recreation, while others say people can’t even go scuba diving.
In one glaring recent example, the advocacy group Oceana U.K. found evidence that the United Kingdom allows bottom trawling in many of its MPAs. Bottom trawling is a fishing method that’s extremely destructive to sensitive habitat types; it’s been compared to clear-cutting forests to catch rabbits.
“At the end of the day … there’s no one clear definition of what conservation means around the world,” says Angelo Villagomez, a senior fellow at the Center for American Progress who has studied the issue. “One of the negative externalities of the global push to protect 30% of the ocean is that some governments are more concerned with being able to say that they protected 30% of the ocean than they are concerned with delivering meaningful biodiversity protections.”
Villagomez and his colleagues have identified another big issue: According to their new analysis in the journal Conservation Letters, fully one-quarter of the 100 largest marine protected areas — as cataloged in the United Nations and IUCN’s world database of protected areas — are announced but not yet implemented. Many have no clear timeline of when the formal protections might be put into place, or what those regulations might look like.
For now, those areas exist on paper but remain unprotected in the real world. For example, the paper cites the OSPAR MPA network covering 7% of the Northeast Atlantic, which currently appears to have no concrete protections.
This wide range of rules and inconsistent protections makes it harder to protect the ocean — or to count it toward 30×30 goals.
Governments are not supposed to submit anything to the world database of protected areas until something is designated, “but they do, and that’s just the reality,” says Villagomez.
But here’s the biggest problem: The study found that many of the world’s largest MPAs lack the scientific knowledge, funding, and political support to be effective.
“We know that MPAs work when they are well designed and provided the funding to operate,” Villagomez told me. “But for about one-third of the MPAs we studied, based on everything we know about protected area science, they will never result in positive outcomes for biodiversity.”
The conclusions of these two papers are clear: Too many marine protected areas are poorly designed and sited in places where the species they’re ostensibly trying to protect do not actually live. Also, too many allow destructive extractive industries to operate, limiting the benefits of any protection.
Despite these setbacks, Villagomez remains optimistic about the future of MPA-based protections.
“The good news is that this works really well about one-third of the time — if you play baseball and you hit the ball 300 out of 1,000 times, you’re going to the Hall of Fame,” he says. “There’s a ton of science that shows that well-designed well-implemented MPAs work, and for one-quarter of the MPAS we looked at, they’re well designed and are just lacking funding for implementation.”

Editor’s note: Mass media news about war raises concerns about death, injury, and refuge of humans, the war on nature is rarely highlighted. But warfare always means ecocide on a large scale and wildlife and nature often take more time to recover than it is capable of. In Ukraine, 80% of wildlife is already on the brink of extinction, with the Russian aggression even more species and individual animals are getting lost. Therefore it’s a relief to have organisations like UAnimals who rescue pets and wildlife in emergency situations and raise international awareness about the destruction in nature and national parks.
The Ottawa Convention also referred to as the “Mine Ban Treaty,” prohibits the use, stockpiling, production, and transfer of anti-personnel landmines (APLs). Some key current and past producers and users of landmines, including the United States, China, India, Pakistan, and Russia, have not signed the treaty.

For Ukrainian activists, rescuing the dogs of war — not to mention the cats, swans, bats, bears and other wildlife — often means putting their own lives on the line.
Saving Ukraine’s injured and displaced animals during wartime often means seeing the worst elements of Russian cruelty.
“When a territory is liberated, our team goes there and we speak with the people who survived the occupation,” says Olga Chevhanyuk, chief operating officer of UAnimals, Ukraine’s largest animal-rights organization. “And each time we hear that when the Russians entered the town, they started shooting animals for fun, starting with dogs just walking the streets and ending with huge farms and shelters. Sometimes it’s probably a matter of manipulation, getting people scared. But mostly it’s no reason at all, just because they can.”
Originally founded to oppose inhumane conditions in circuses, the nonprofit UAnimals has shifted its mission to rescuing and caring for domestic animals and wildlife devastated by Russian aggression.
Working with local volunteers and shelters, they’ve helped tens of thousands of animals since the war began a year ago, including dogs and cats, horses, deer, swans, birds of prey and bats — even large predators like bears. In January alone they rescued more than 9,600 animals, provided food and medicine to thousands more, rebuilt shelters, and helped fund operations throughout the country.
They’ve also found themselves purchasing supplies not traditionally used in animal rescues.
“Before the war, you never think of buying helmets for your team,” Chevhanyuk says.
And then there’s the human toll: The nonprofit has contracted with psychologists to provide on-demand assistance to its team in the field. “So now they can have a session with the psychologist when they’re overwhelmed,” she says.
But this is all about saving more than individual animal lives and human minds. It’s about saving the soul of a country.
A Crime Against Nature
UAnimals has started calling the Russian war an ecocide — the deliberate destruction of the natural environment.
“Nowadays 20% of Ukraine’s nature conservation areas are affected by war,” Chevhanyuk says. “Russians occupy eight national reserves and 12 national parks, and some of the national parks are land-mined. Holy Mountains National Park is 80% destroyed. Some of them are destroyed 100%, meaning there are no plants, no animals, and no buildings which people use to heal animals. The land is littered with remains of destroyed objects, like tons of oil and burned products.”
Landmines are among the worst problems. They kill humans and animals indiscriminately, start fires, and will take years to mitigate. About 62,000 square miles of Ukraine may be contaminated with landmines. “This is greater than the size of Illinois,” according to information provided by a U.S. State Department official. “The United States is investing $91.5 million over the coming year to help the government of Ukraine address the urgent humanitarian challenges posed by explosive remnants of war created by Russia’s invasion.”
Cleaning up the pollution will require even more funding and effort. The war has caused at least $37 billion in environmental damage, a Ukrainian NGO said in November.
UAnimals predicts it could take more than a decade to repair the damage, but Ukraine’s wildlife doesn’t have that much time. “More than 80 species of animals in our country are on the verge of extinction and may completely cease to exist due to Russian aggression,” Chevhanyuk says. “Some of them are the steppe eagle, black stork, brown bear, Eurasian lynx, barn owl and eared hedgehog.”
While many of these species also exist in other countries, Chevhanyuk says wildlife has been an important element of Ukrainian folksongs, art and symbology — the very fabric of its culture — for centuries. “Being humane and treating animals as something really important and equal — this is one of the things which differs us a lot from Russians. And that’s, I believe, a part of our future victory.”
Moving Forward
UAnimals continues to ramp up its fundraising and recovery efforts while expanding its network of shelters outside the country — a necessary step, as Ukrainian shelters and reserves are rapidly filling to capacity with animals too wounded ever to be released back into the wild.
“We have big shelters for bears, for example,” Chevhanyuk says, “but they are already full. I’m afraid that if something happens, we’ll need to bring these animals abroad. So we are very grateful to all our partners in different countries because there’s a big need right now.”
The organization is also tapping back into its activist roots to bring international attention to conditions in Ukraine. In February they organized Stop Ecocide Ukraine rallies in four U.S. cities — Atlanta, Austin, New York and San Antonio — that each attracted hundreds of people.
In a way, this is a return to form. “We used to create huge animal-rights marches in 30 Ukrainian cities every September,” Chevhanyuk says. “But since the war started, we are more focused on the emergency.”
And the international community has started to take notice. Last month the Parliamentary Assembly of the Council of Europe passed a resolution to “build and consolidate a legal framework for the enhanced protection of the environment in armed conflicts” — steps that support establishing ecocide as a new international crime.
“From a legal perspective, this is really encouraging,” says Jojo Mehta, cofounder and executive director of Stop Ecocide International, “because if you put severe harm to the living world on the same level as severe harm to people, if you say ecocide is as bad, wrong and dangerous as genocide, you’re creating a mental rebalance.”
It could still take years for ecocide to become international law. Meanwhile, the destruction of Ukraine continues, as do recovery efforts.
“If our team knows there is an animal to rescue,” Chevhanyuk says, “they will go in.”

Editor’s note: It’s a coast – not a beach, we forget that when our society talks about going to the beach. A beach is for basking in the sun, getting a drink, and dabbling in the water. But a coast is far more than an entertainment place for humans, it’s a habitat for a variety of animals and plants. Sand mining is a threat to these ecosystems and criminals operate it illegally. Construction companies need sand for their concrete as the demand for buildings soars. They seal the planet by destroying coastlines – and beaches.
While beaches are being stolen in poor places, they are being nourished(replenished) in wealthy places. Beach nourishment is the process of placing additional sediment on a beach or in the nearshore. A wider and higher beach can provide storm protection for coastal structures. Sediment is commonly dredged offshore and pumped directly onto the beach, dumped nearshore by a hopper dredge, or occasionally sourced from an inland location. It is an exercise in futility that destroys natural ecosystems and subsidizes wealthy beachfront homeowners at taxpayers’ expense, particularly as worsening storms resulting from climate change demand investment in more permanent solutions to beach erosion. The sea level will rise and people living there will have to move.
It is time to stop building infrastructure and trying to control nature.

Increasing demand for this seemingly abundant and common material harms human and natural communities — and fuels a lucrative and dangerous illegal industry.
Coastal ecosystems — including oyster reefs, sandy beaches, mangrove forests and seagrass beds — provide important habitat for marine life and food and recreation for people. They also protect shorelines from waves and storms. But these precious systems face serious threats. This article looks at what put them at risk, along with examples of efforts to restore and protect important coastal ecosystems around the world.
We need to talk about sand
Most people don’t realize that these humble grains — that ubiquitous stuff of vacations, ant farms and hourglasses — are the second-most used natural resource in the world after water. According to a 2019 report from the United Nations Environment Programme, we use more than 55 billion tons of it per year — nearly 40 pounds per person per day.
And a lot of that sand comes from illegal activity, involving criminal gangs who mine, smuggle, and kill for the precious material.
The Building Blocks of Modern Society
Sand — legal or otherwise — gets used to enhance beaches, extract petroleum through hydraulic fracking, fill land under buildings, and make computer chips.
But the biggest amount by far — an estimated 85% of the sand mined globally — goes into making concrete. Concrete combines two key ingredients: cement, a binding agent made from calcium or other substances, and aggregate, which is either sand or a combination of sand and gravel. Quality concrete requires jagged and angular aggregate grains — a quality found in only a tiny fraction of the worlds’ sand, most of it on beaches and in rivers. This sand also is easy and cheap to mine, and it’s located close to much of the construction taking place around the world.
According to the United Nations Environment Programme, world consumption of aggregate for all uses exceeds 40 billion metric tons (44 billion U.S. tons) a year — an estimate that’s likely on the conservative side and represents about twice the amount of sediment carried annually by all the world’s rivers. (Sediment from land rocks is the source of most coastal sand, which also comes from shells and marine organisms pulverized by waves, the digestive tracts of coral-eating fish, and the remains of tiny creatures called foraminifera.)
Not surprisingly, UNEP calls management of sand one of the greatest sustainability challenges of the 21st century.
The organization also warns about sand mining’s serious consequences for humans and the natural environment.
Removing beach sand leaves coastal structures more vulnerable to erosion even as climate change raises sea levels and makes storms more intense. Transporting sand generates carbon dioxide emissions. Sand mining has political and cultural consequences, including effects on the tourism industry, and creates noise and air pollution.
Coastal sand mining also destroys complex ecosystems. The microorganisms, crabs, and clams that live in beach sand are important food sources for birds. Sea turtles and several bird species nest on sandy beaches. Seagrass, an important food source and habitat for marine residents, needs sandy ocean floor to grow. Stretches of underwater sand provide habitat for sea stars, sea cucumbers, conchs, and other critters, and are feeding grounds for flounder, rays, fish, and sharks.
Removing sand also affects water quality in the ocean and depletes groundwater.
Stolen Sand
Yet this harm is not the only issue. Increasing demand for sand has created a vast illegal industry resembling the organized criminal drug trade, including the same violence, black markets, and piles of money — an estimated $200 to $350 billion a year. Of all the sand extracted globally every year, only about 15 billion metric tons are legally traded, according to a report from the Global Initiative Against Transnational Organized Crime.
Pascal Pedruzzi, director of UNEP’s Global Resource Information Database-Geneva, became aware of illegal sand mining when the Jamaican government asked UNEP in 2014 to find out why the island had a serious beach erosion problem.
“There was a lot we didn’t know about sand extraction, including how much was being taken,” he says.
Or from how many places: Sand is mined from coastal environments in at least 80 countries on six continents, according to the 2022 book Vanishing Sands, written by several geologists and other experts on coastal management and land rights.
The book outlines a litany of sand crimes, from seemingly small to massive. In Sardinia, Italy, airport officials have seized about 10 tons of sand over 10 years, much of it carried in thousands of individual half-quart bottles. In Morocco, criminals removed as many as 200 dump trucks of sand a day from massive dunes lining the Atlantic coast.
According to Africa’s Institute for Security Studies, illegal sand mining in Morocco is run by a syndicate second in size only to the country’s drug mafia. It involves corrupt government and law enforcement officials and foreign companies. Much of the Moroccan sand, for example, ends up in buildings in Spain.
In India demand for sand tripled from 2000 to 2017, creating a market worth 150 billion rupees, just over $2 billion. Multiple diverse and competing “sand mafias” run mining sites surrounded by armed private security guards. Their weapons likely are obtained illegally, given the difficult process of acquiring guns legally in India.
The NGO South Asia Network on Dams, Rivers and People reports hundreds of deaths and injuries related to illegal sand mining in India each year, including citizens (adults and children), journalists, activists, government officials, and law enforcement.
There are similar stories in Bangladesh, Cambodia, elsewhere in Africa, and in the Caribbean — almost everywhere sandy coastal areas can be found.
How to Solve the Problem
UNEP has begun tackling the problem of sand mining, putting forth ten recommendations that include creating international standards for extracting sand from the marine environment, reducing the use of sand by using substitutes, and recycling products made with sand.
While these recommendations target legal sand mining, more responsible management and reduced overall demand also should make illegal mining less lucrative and, therefore, less common.
“The good news is there’s a long list of solutions,” says Peduzzi. “We start by stopping the waste of sand. We can make the life of buildings longer, by retrofitting them instead of knocking them down. Maybe change the use of a building over time, as a school first and then 50 years later, a place for elderly people. When a building needs to be destroyed, crush and reuse the concrete. Build with wood, bricks, adobe, and straw.”
Building with straw also could reduce burning of crop waste. Every year, India produces 500 million tons of straw but burns 140 million tons as “excess.” One company there, Strawcture Eco, is using straw to create wall and ceiling panels that are fire resistant, insulating, and sustainable.
Alternatives to sand in concrete include ash from waste incineration and aluminum smelting waste. Peduzzi notes that ash creates concrete that is about 10% less solid, but points out, “that is still pretty good. You can use it to make buildings, but maybe not a bridge.”
The UNEP report notes that involvement from industry, the private sector, and civil society is vital in solving the problem. For example, shifting away from building with concrete will require changing the way architects and engineers are trained, acceptance by building owners, and new laws and regulations.
“We rely on sand, as a commodity,” Peduzzi says. “But we also need to realize its ecosystem services. We must be wiser about how we use it.”
UNEP hopes to collect solutions into a single, accessible online location (although it currently lacks funding for the effort). The idea is to create a hub for policies and technological solutions, Peduzzi says, and to develop best practices for them. The Global Initiative report on India also calls for a website for tracking illegal sand mining hosted by a think-tank or journalism agency — a sort of crime-spotters portal where people could anonymously upload evidence.
Shifting Sands, Shifting Thinking
William Neal, an emeritus professor at Grand Valley State University in Michigan and one of the authors of Vanishing Sands, suggests in an email that finding sand substitutes is not enough. Coastal communities, he says, need to retreat from rising seas rather than build more hard structures such as seawalls. This “shoreline engineering” often destroys the very beaches it is intended to save, he explains, and the long-term cost of saving property through engineering often ends up exceeding the value of the property. Seawalls also tend to simply shift water elsewhere, potentially causing flooding and significant damage along other parts of the shoreline.
Peduzzi also espouses shifts in thinking, including how we get around in cities.
“Instead of building roads for cars, build subways,” he says. “That moves people faster and gets away from fossil fuels. The icing on the cake is that when digging subway tunnels, you are getting rocks, generating this material instead of using it. Cars are not sustainable — not the material to make a car itself or the roads and parking lots.”
Without systemic changes, the problem of sand removal is only going to grow bigger as the population increases and people continue to migrate from rural to urban areas, increasing the demand for infrastructure like roads and buildings.
“The problem has been overlooked,” Peduzzi warns. “People need to realize that sand is just another story of how dependent we are on natural resources for development.”

Editor’s note: Sharks are beautiful, intelligent creatures, but they have been overexploited for decades. Because of their “high market value” industrial fisheries hunt sharks for their fins and other body parts. But it’s difficult to control the protection of the sea predators when they move to unprotected zones or international and local fleets fish in other countries’ fishery zones. The brutal killings of adults, babies, and even pregnant sharks happen while our culture is focused on buying more stuff and attending distracting events.
If sharks went extinct, it would set off a chain reaction. Sharks play an important role in the food chain. Smaller animals like shellfish may go extinct if there were no sharks to eat seals, for example. That would create a ripple effect, causing mass die-offs of otters, seals, and many types of fish due to food scarcity. The chain reaction would continue until its effects were felt on land, with fisheries collapsing in a matter of years. When will humanity wake up and start living with – not against other precious beings?

Shark awareness day
Every year on July 14th, we celebrate Shark Awareness Day. It is not just a tribute to one of nature’s most misunderstood creatures; it is a call to action. Sharks have cruised the oceans for over 450 million years, playing a vital role in keeping marine ecosystems healthy. But today, these apex predators find themselves under increasing pressure, with many species teetering on the brink of extinction.
Sharks: More Than Just Jaws
Hollywood might portray sharks as mindless killing machines, but this couldn’t be further from the truth. Sharks come in a staggering variety of shapes and sizes, from the filter-feeding giants like the whale shark to the sleek and speedy blue shark. They possess incredible senses, like electroreception, that allows them to detect electrical fields emitted by prey, and an amazing ability to navigate vast distances.
As apex predators, they help maintain the balance by regulating the populations of species below them in the food chain. This includes controlling the numbers of mid-level predators and helping to ensure species diversity among smaller fish and invertebrate populations. Their feeding habits help keep marine ecosystems healthy and functional. For instance, by preying on weak or sick individuals, sharks help prevent the spread of disease and ensure a healthier gene pool within the prey population. Their disappearance could have devastating consequences, leading to population explosions of prey species and ultimately, the collapse of entire ecosystems.
A Cause for Alarm: Why Are Sharks Endangered?
Despite their importance, many shark species are alarmingly close to extinction. According to the International Union for Conservation of Nature (IUCN), over one-third or 30% of shark species are either vulnerable, endangered or critically endangered. Some of the most threatened species include the Great Hammerhead, the Oceanic whitetip, and the Basking shark.
The main culprit behind this is overfishing. Driven by demand for shark fins (a prized ingredient in shark fin soup) and meat, millions of sharks are caught every year, often through unsustainable practices like finning, where fins are removed and the body discarded.
Another major threat is habitat loss. Sharks rely on healthy coral reefs and mangroves for breeding and feeding. However, these vital ecosystems are being degraded by pollution, climate change, and coastal development.
A Ray of Hope: Conservation Efforts Underway
The silver lining in the story of sharks is the growing awareness and effort towards their conservation. Governments, NGOs, and international bodies are working together to protect these magnificent creatures:
- Protected Areas: Many marine protected areas (MPAs) have been established to provide safe havens for sharks where fishing is restricted or banned. One notable example of a Marine Protected Area (MPA) that provides a safe haven for sharks is the Chagos Marine Reserve in the Indian Ocean. This reserve is one of the world’s largest marine protected areas and encompasses a variety of marine environments. It offers significant protection to various shark species, among other marine life, by enforcing strict regulations that limit fishing and other extractive activities.
Another example is the Jardines de la Reina National Park in Cuba, which has been particularly successful in conserving shark populations. This MPA provides a refuge for several species of sharks and has implemented strict no-take policies and eco-tourism guidelines that help maintain the health and biodiversity of its waters.
Deadly Predators
Deadly predators,
Under the sea and on land
But, what’s more deadly?

Or the end of marine life?

- Regulations and Bans on Shark Finning: Shark finning, the brutal practice of removing a shark’s fins and discarding the rest of the body, has prompted global action through stringent regulations and international cooperation. Many countries now enforce laws that require sharks to be landed with fins naturally attached, enhancing sustainable practices and compliance. Furthermore, international agreements like CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) play a critical role in regulating the trade of endangered shark species to ensure their survival. These efforts are crucial in curbing unsustainable exploitation, promoting marine conservation, and supporting the recovery of shark populations worldwide.
- Sustainable Fishing Practices: Minimizing bycatch, the accidental capture of non-target species in fisheries, is crucial for preserving marine biodiversity, including sharks. Sustainable practices such as gear modification, implementing time and area closures, and employing bycatch reduction devices can significantly reduce unintended catches. Regulations that require fisheries to use circle hooks and turtle excluder devices (TEDs) help prevent the capture of non-target species like sharks and turtles. Additionally, real-time management of fisheries based on immediate data and promoting consumer awareness through eco-labeling, as mandated by organizations like the Marine Stewardship Council (MSC), can drive demand towards sustainably harvested seafood. These strategies not only help conserve marine species but also enhance the overall health of marine ecosystems and support the economic stability of fishing-dependent communities.
This Shark Awareness Day, let’s not only admire the majestic Great Whites and the elusive deep-sea dwellers but also ignite a global commitment to safeguard their future. Every shark species plays a pivotal role in marine ecosystems, balancing marine life and ensuring the health of our oceans.
Today, we must transcend admiration and take decisive action. Let’s pledge to protect these magnificent creatures, understanding that saving sharks is fundamentally about preserving the entire marine ecosystem. By protecting sharks, we are not just saving individual species; we are investing in the health and sustainability of our entire ocean. Join us in this crucial mission—educate, advocate, and participate. Together, we can turn the tide for sharks and secure a vibrant future for our blue planet.
